What is the Mega CD?
The Mega CD is a CD ROM drive that plugs into the expansion port on the side of the Megadrive and allows specially written CD software to be played on the Megadrive. The Mega CD could also play normal music CDs both 5 and 3 inch discs and could play CD+G discs. The Mega CD also improved the graphics and sound of the Megadrive. There are 2 versions of the Mega CD that are technically the same but with different casings. The Mega CD 1 Sat underneath the Megadrive 1 and featured a motorized front loading CD drive. The Mega CD 2 was released at the same time as the Megadrive 2 and attached to the side of either version of the Megadrive and had a top loading CD drive.
